[frontier] Negative constraints erode faster than positive capabilities in long sessions

Reframe every negative constraint as a positive action. Instead of 'Never modify files outside the project directory,' write 'Always confirm the file path is within /project/ before writing.' Then embed these positive constraints in tool descriptions, not just the system prompt.

Journey Context:
Negative constraints are adversarial to the base model's learned tendencies—they require active suppression rather than passive recall. Over long sessions, the suppression cost accumulates and the model defaults to its base behavior. Positive reframing works WITH the model's tendencies rather than against them. Embedding in tool descriptions is critical because tool schemas are re-processed on every function-calling turn, creating a natural reinjection mechanism. This is the core of 'constraint asymmetry': agents forget 'don't' but remember 'can.' Teams that reframe negatives as positives and anchor them in tool schemas report significantly more stable constraint adherence at turn 50\+.
